2. Description of the Related Art The output of a transmission such as a forklift truck is generally transmitted from an output gear to an output yoke, and is transmitted to an axle side by a hook type joint or the like. That is, as shown in FIG. 4, the output gear 41 and the output yoke 44 of the transmission are spline-coupled. The output yoke 44 is connected to a driven shaft 45 on the axle side via a hook type joint 43.

When fitting the snap ring 5 into the ring groove 440, the output yoke 44 is first assembled to the output gear 41. Next, while maintaining this state, the snap ring 5 is attached to the pliers 49.
The ring groove 440 is fitted into the ring groove 440 while expanding the diameter of the ring. A similar connection method between the yoke of the hook joint and the gear is also used for power transmission between the propeller shaft and the final reduction gear. In this case, the yoke side transmits power and the input gear of the final reduction gear operates so as to receive power, but the other aspects are the same.

However, the mounting work of the snap ring 5 is a very difficult work. That is, when the output yoke 44 is inserted and the step portion 441 is brought into contact with the step portion 441 of the output gear 41, the groove end 442 of the ring groove 440 becomes the end portion 413 of the output gear 41.
Since it is close to the ring groove 440, the working space around the ring groove 440 is extremely limited.

It is necessary to firmly push the output yoke 44 to the right in FIG. 4 with one hand so that the ring groove 440 thereof is located outside the end portion 413 of the output gear 41. Then, while maintaining such a state, the diameter of the snap ring 5 must be enlarged by the pliers 49 using the other hand and carefully fitted into the ring groove 21.

At this time, if the diameter of the snap ring 5 is expanded too much without applying any force, the snap ring 5 may be plastically deformed and become a defective product. Therefore, delicate skill is required to adjust the applied force. As described above, the work of mounting the snap ring 5 is a difficult work that requires a great deal of skill and attention. This is the same when the yoke of the hook type joint is connected to the input gear of the final reduction gear.
